The wheel on a car completes
25 revolutions and travels about
35.325 meters. Rounded to the
nearest centimeter, what is the
diameter of the wheel? Use 3.14 for pi.
Answer:
Step-by-step explanation:
Let d be the diameter of the wheel.
Circumference = πd
(35.325 m)/(25 revolutions) = (1.413 m)/revolution
πd = 1.413
d = 1.413/π = 0.45 m

please answer these 5 questions:). (for a practice test graph photo up above) (question 9) use the graph to find the slope and y-intercept. (question 10) steve started with $50 and saved $20 each week. what is the equation when y represents the amount of savings and x represents weeks? how much will steve have after 4 weeks? (question 11) brittany started with $300 and spent $40 per week. what is the equation when y represents savings and x represents weeks? how much will brittany have after 4 weeks? (question 12) convert to slope-intercept form. -5/8x - 1/2y = 1 (question 13) convert to slope-intercept form. 9 + 3x = 6y
Answer:
9. slope: 1/2 y-int: -4
10. y=20x+50
11. y=-40x+300
12. i dnt know
13.9/6+3/6x=y or 1.5+0.5=y
Step-by-step explanation:
10. starts at 50, goes up by 20 per week
11. starts at 300, goes down 40 per week
13.
9+3x=6y
9/6+3/6x=y or 1.5+0.5=y

James has $10 in 5-cent and 10-cent coins in his change jar and counts 157 coins in total. How many 10-cent coins does he have?
Show working out!!
Answer:
10 cent coins = 43
Step-by-step explanation:
x = 10 cent coins
y = 5 cent coins
x + y = 157, then y = 157 - x
$10 = 1000 cents
0.10x + 0.05y =1000
substitute for y:
0.10x + 0.05(157 - x) = 1000
0.10x + 7.85 - 0.05x = 1000
combine like terms:
0.05x = 2.15
x = 43
y = 114
Express y in terms of x
Answer:
y = 3x
Step-by-step explanation:
to get y we multiply x by 3 so we have that y = 3x.
Find the value of x.

Ernie is . All of these points on the same line because the slope between (0, 0) and (3, 3) equal to -4.
Answer:
Ernie is incorrect.
Step-by-step explanation:
I suppose that we want to see if Ernie statement is correct or not.
Suppose that we have a line that passes through the points (x₁, y₁) and (x₂, y₂)
The slope of that line can be calculated as:
slope = (y₂ - y₁)/(x₂ - x₁)
In this case, we know that the line passes through (0, 0) and (3, 3), then the slope of this line is:
slope = (3 - 0)/(3 - 0) = 3/3 = 1
Then Ernie got the slope wrong, which means that he is wrong.

James raises chickens. He tracks the number of eggs his chicken lay at the end of each week. Is this relation a Function? Explain
Answer:
Yes it is a function.
Step-by-step explanation:
It is given that James raises chickens in his farm. and the chicken laid eggs on each day. James keeps a track of the number of eggs that his chicken laid at the end of each week.
This is a function because according to the definition of a function, if each of he input corresponds to exactly one output, then that relation is called as a function.
In this case, every week the chickens lay different number of eggs. So every week corresponds to the different number of eggs laid by the chicken. So it is a function.
Answer:
Yes it is a function because there is a domain/Input for each Range/Output

Determine the Equation of the line Perpendicular to 2x -3y +5= 0 and passers through (-6,-3)
9514 1404 393
Answer:
3x +2y +24 = 0
Step-by-step explanation:
In general, the equation of a perpendicular line can be found by swapping the coefficients of x and y, then negating one of them. The value of the constant will be what is required to make the line pass through the given point.
The equation will be of the form ...
3x +2y +c = 0
At the given point, (x, y) = (-6, -3), we have ...
3(-6) +2(-3) +c = 0 . . . . substitute the given point coordinates
-18 -6 +c = 0 . . .simplify
c = 24 . . . . . . . . add 24
The general-form equation for the line is ...
3x +2y +24 = 0 . . . . . shown in blue in the attachment

Ana has a hypothesis that girls get up earlier and, as a result, usually enter Ana's Donut Shop before boys do. To
test her hypothesis, she spends 10 mornings asking the first 3 people to enter her shop whether they are a boy
or a girl.
The data she collects is given in the table below. "G" represents a girl, and "B" represents a boy.
Drag the bars to make a relative frequency plot that shows the proportion for each possible number of girls in
the first 3 customers in a day.
